The other bodies are imported "via yade", athough not directly. Still you have access to the bodies as O.bodies[theProblematicID] > Besides, the above reported error only appears when I defined FrictMat in the script. When I define only PolyhedraMat and use only the following engine, the problem did not occur. If you use only PolyhedraMat, all the needed dispatchers for material-shape combinations exist. For FrictMat and PolyhedraMat, you create a FrictPhys (Ip2_FrictMat_PolyhedraMat_FrictPhys) but at the same time from Facet and Polyhedron you create PolyhedraGeom (Ig2_Facet_Polyhedra_PolyhedraGeom). And there is no Law2 for PolyhedraGeom and FrictPhys.. You have either implement the Law2, or choose such combination of shapes, materials, Ip2 and Ig2 such that all resulting IGeom+IPhys combinations can use existing Law2.
